Abstract

In animal models, when swallowing is experimentally prevented in utero, bowel length and weight are reduced, and villus height, crypt depth, and villus function are retarded. Little is known about the intestinal histology in infants with gastrointestinal (GI) tract anomalies. We examined the histological architecture of the intestine in neonates with GI anomalies in comparison to that of normal fetuses. Villus height, area, and length and crypt depth of normal fetuses were quantified in the proximal small bowel (n = 11) and measurements compared to those of surgical specimens of neonates with congenital anomalies of the GI tract (n = 16). Villus height and area and lamina propria height and area increased linearly from 8 to 24 weeks of gestation. In infants with anomalies of the GI tract, the villi were blunted and lacked normal histological architecture, the crypts were disorganized, and the crypt depth was significantly decreased (p = 0.004). Enterocyte height and area were significantly greater in neonates with congenital anomalies of the GI tract. The intestinal histology in neonates with congenital anomalies of the GI tract differs significantly from that of normal fetuses.
